Checkbox or switch widgets are linked to which type of variable?

Checkboxes and switch widgets are designed to represent a binary state: either 'on' or 'off', 'checked' or 'unchecked'. This is inherently a Boolean state, which aligns perfectly with Boolean data types that can hold one of two values — true or false.

When a checkbox or switch is used in an application, it typically binds to a Boolean variable. When the user selects the checkbox or switches it on, the Boolean variable is set to true, and when it is deselected or turned off, the variable is set to false. This clear mapping between the two states allows the application to easily understand and respond to user inputs regarding binary choices effectively.

For other variable types like Text, Integer, and Date, they do not match this binary requirement. Text fields would capture string input, Integer would store numerical values, and Date would handle date entries, none of which are suitable for representing simple true/false scenarios that checkboxes and switches inherently manage.
